  4. Problem • 4-Stroke engines are inefficient • Implement a 2nd power cycle • Use less fuel while maintaining power • Water injection system • Electrically Controlled Engine

  5. 6-Stroke Engine 1. Intake of air + fuel 2. Compression 3. Combustion 4. Re-compression 5. Water Injection 6. Exhaust

  6. Design A • Two considered design alternatives • Camshaft Modification • Mechanically controlled • Extend crankcase to allow room • Manufacture camshaft

  7. Design B • Electrically Controlled Engine • Remove cam controlled valves • Replace with solenoid actuated valves • Added capability between 4+6 strokes • Head redesign

  8. Issues • Injection System • C programming • Space Requirements • Water in Fuel Injector • Economics • Engine Testing • Pressure • Temperature • Emissions testing • Orsat failure • Gas chromatography • Chemistry Department • Dynamometer testing • Fastbikes U.S.A. • Engine Modification • John Farris-GVSU
